It is found during the use of border, still remains following defect：
When Debugging message is exported by I/O interface, if thering is user operating equipment just at this time, debugging
The output of information will be mixed in together with the I/O operation of user, can seriously affect user's operation in this way so that user experience is non-
It is often poor.For example, such a scene, maintenance personnel has found that certain equipment breaks down, and in order to investigate fault point, is just following behaviour
Make：The debugging switch for opening modules A, opens the debugging switch of module B, and modules A prepares 2 Debugging message of output, is respectively
Aaaaa, AAA；Module B prepares 3 Debugging message of output, is bbbb, BBBB, b-b-b respectively；And at this point, maintenance personnel is accurate
It is standby to input order line " show version " (checking device version information) simultaneously, then when maintenance personnel just inputs " show
When ver ", the output of possible modules A and module B come simultaneously, and the display on device end at this time is likely to occur as soon as letter
The chaotic interspersed phenomenon of breath, such as " show veraabbbbaaa BBAAABB b-b-b ".The defeated of maintenance personnel had both been affected in this way
Enter, causes maintenance personnel to need to re-enter order, while the output of A, B module also mixes, and can not check completely.
The reason of leading to the above problem, is that the output of Debugging message is uncontrollable, and multiple tasks export together, and and
The I/O operation of user mixes；This is also to be influenced by tasks of embedded system scheduling, and multiple tasks operate same simultaneously

Description of the drawings
Fig. 1 is the flow chart for the method for intelligently exporting Debugging message in the embodiment of the present invention in embedded device.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described in further detail.
Shown in Figure 1, the embodiment of the present invention provides a kind of method that Debugging message is intelligently exported in embedded device, packet
Include following steps：
S1：A buffer area for multistage pipeline information, all debugging are added in the management terminal of embedded device
Information is not directly output to I/O interface, but is first buffered in the buffer area；Default probe interval period and free time
Threshold value, initialization time point when by start to process are denoted as time point value T1, are transferred to S2.
S2：Within each probe interval period, judge whether user has I/O operation, if so, being transferred to S3；Otherwise, it is transferred to
S4。
S3：Execute the I/O operation of user；Record current time is updated using current time as new time point value T1
Time point value T1, is transferred to S7.
S4：The difference between current time and time point value T1 is calculated, judges whether the difference is more than free time
Threshold value is transferred to S5 if so, showing to be currently at a kind of idle state；Otherwise, show to be currently at a kind of busy state,
It is transferred to S7.
S5：Check in buffer area whether there is Debugging message to be output, if so, being transferred to S6；Otherwise, it is transferred to S7.
S6：The Debugging message of specified number of entries is output to I/O interface, is transferred to S7.
S7：Judge whether to need to enter next probe interval period, if it is not, then terminating；If so, return S2, wait for into
Enter next probe interval period, i.e., continues circular treatment since S2.Such circular treatment can then reach intelligent prison
Measurement equipment state, intelligence export the effect of Debugging message, i.e., do not influence the I/O operation of user, and can reach and smoothly check debugging
The purpose of information.
When specific operation, management terminal described in S1 can be virtual terminal VTY (Virtual Teletype
Terminal), or entity terminal, such as serial interface, AUX interfaces.
The size of buffer area described in S1 can carry out real-time configuration modification according to user demand.Specifically, buffer area
Size, may be used first preset an initial value, then provide configuration interface carry out configuration modification in real time for user, in this way may be used
To meet the needs of under different scenes and application.Also, when buffer area remaining space deficiency, it can take but be not limited to following
Processing mode：Debugging message before new Debugging message is covered, or directly abandon new Debugging message.
In addition to this, probe interval period described in S1 can voluntarily be specified according to the demand or design of producer, but one
As can be set as 0.5 second~2 seconds.Set the probe interval period to a very short value, reason for this is that：The pipe of embedded device
Reason terminal is all that can only monitor in present communications channel (fd for communication) whether have I/O operation, if present communications channel
It (fd), then can (it be exactly detection to I/O operation that " long-time " is corresponding herein for a long time without any data input and output in
Time interval) it is blocked at communication port, other objects can not be thus monitored (for example, can not be to the caching added
Area is monitored).Therefore, for the output of quick, intelligent control Debugging message, it is proposed that the probe interval period is set as one
A very short time, and the probe interval period is smaller, it is faster to the response speed of user's operation.
In addition, probe interval period described in S1 can be in real time adjusted according to exterior arrangement and instruction, need not make
Use fixed value.It specifically, can be by reserved parameter/configuration interface to visiting after presetting the probe interval period described in S1
It surveys gap periods and carries out real-time configuration modification.
Similarly, free time threshold value described in S1 also suggests not using fixed value, and can be based on each management
The concrete condition of terminal carries out what outside configured in real time.It specifically, can be with after presetting free time threshold value described in S1
Real-time configuration modification is carried out to free time threshold value by reserved parameter/configuration interface.
But it should be noted：The setting of free time threshold value is bigger, then user is in continuous operation, when intermediate pause
Between can be longer, but when user stops operation, until the time interval of Debugging message output is also longer；Conversely, empty
Threshold value setting is smaller between idle, then for user in continuous operation, the intermediate dead time is shorter, otherwise in user's operation
In pause interval, and there may be Debugging message defeated just as the dead time is long the free time threshold value of setting (be more than)
Go out, but when user stops operation, until the time interval of Debugging message output is also shorter.
When practical operation, when Debugging message being output to I/O interface described in S6, a Debugging message can be only exported,
A plurality of Debugging message can once be exported.But the Debugging message of output is more, then slower to the response time of user's operation.Every time
How many Debugging message are exported, default settings (such as acquiescence output one every time) can be first used, then, be matched according to outside
It sets and instructs and adjusted in real time.Specifically, when Debugging message being output to I/O interface described in S6, the Debugging message of output
Item number first exported according to the item number of default value, then according to exterior arrangement and instruction to the item number of the Debugging message of output
It is adjusted in real time.
In addition, for the Debugging message for enabling buffer area to reserve enough spaces to store subsequently newly-increased, for
The Debugging message of output then needs the buffer area for discharging its occupancy.Specifically, Debugging message IO is output to described in S6 to connect
After mouthful, the Debugging message of this output is deleted from buffer area.
The embodiment of the present invention also provides the system that Debugging message is intelligently exported in a kind of embedded device, including initial setting up
Module, Debugging message output module and detection judgment module；
Wherein, the initial setup module is used for：Added in the management terminal of embedded device one for cache tune
Try the buffer area of information；Probe interval period and free time threshold value are preset in the management terminal of embedded device, will be opened
Initialization time point when beginning to handle is denoted as time point value T1, and output processing signal is sent to Debugging message output module；
The Debugging message output module is used for：Receive output processing signal after, within each probe interval period, when with
When family does not have I/O operation, judge that the difference between current time and time point value T1 is more than free time threshold value, and buffer area
Inside there is Debugging message to be output, then Debugging message is output to I/O interface, judges signal to detection judgment module transmission；
The detection judgment module is used for：It receives after judging signal, judges whether to need to enter next probe interval period,
If so, sending output processing signal to Debugging message output module, waits for and enter next probe interval period；Otherwise, stop
Work.
Intelligently exported in the present invention Debugging message method can flexibly, intelligence monitoring device idle state, take
The method that Debugging message is exported under idle state, to avoid the I/O operation conflict with user, and then improves the operating body of user
It tests, increases the ease for use of equipment.Wherein, size, probe interval period and the free time threshold value for the buffer area added,
All it is that can carry out real time modifying by configuration of reservations interface, utmostly meets the different demands of different scenes.And to upper
The layer application function module of Debugging message (export) has no effect and changes, only change management terminal partial code and
The partial code finally exported, change is small, and easy to implement, stability is also very high, has very strong generalization.
The present invention is not limited to the above-described embodiments, and the way of output of Debugging message includes but not limited to be output to IO to connect
Mouthful, can also be to be output to file or log server etc..Here it is output to I/O interface, only a citing.For this
